A 45-year-old South Korean man was charged without detention for allegedly chasing and threatening a student with a deadly weapon, the police said on Friday.

According to Gwangjin District police, the suspect was trying to scold a group of students who were smoking and making loud noises on the street near his house in Gwangjin-gu, Seoul, around 9 p.m. Thursday.

“I tried to warn them but I lost my temper and brought the knife as the students snapped at me,” the suspect said during an investigation.

The man chased a 14-year-old student who was at the site, carrying the lethal weapon while under the influence of alcohol, police said.
